That means that the Realtor is required by law to put the client's interests first, not their own.A legal or ethical violation by a Realtor can result in fines, license suspension or license revocation - not to mention lawsuits and termination by their broker. 

Next step is mutual consent.

The senior consenting to the sale could change that outcome but they would be a fool to consent considering not consenting, preserves their claims against the property.  

They can't even have their own driver license if is not for their parent/guardian consent! 

@Jingru Sui instead of a master lease I basically created my own rental lease that includes written consent to sublease, home modifications, and a few things that were relevant to my objective.

No issues.If the seller's property isn't free and clear, use a Sub-To and obtain title.You can have issues having a lease-option with repairs or rehab required as you'd need the owner's consent and willingness to work with you, a lease doesn't give you owner's rights to encumber a property by contractors or material suppliers, at least cleanly nor might you be able to obtain permits and insurance coverage may be more difficult.....so get title.Stay out of jail and don't get creative in financing without expert, (non-guru) advise.

They did not have my consent when they painted my house.

I looked at the audio recording laws in Ohio and google says it’s a one party consent state.  

If it's a Quit Claim into a revocable trust then the title insurance remains intact and covers the property. 

Moreover i believe First National admitted that although no law permits this practice (unjust enrichment) claimed that Daly had tacitly or otherwise consented by way of making payments on his mortgage for so many months.
